A Design and Research on GMM Precision Flow Pump

Abstract:

A new type of the precision flow pump is developed with the giant magnetostrictive materials as the driving source. Experiment has been conducted to test the performance of the pump with designed key components. The pump as the preloading mechanism, adopting an elastomer instead of a spring, not only simplifies the structure, but also improves the performance of the pump. A design is also made to some key components such as the giant magnetostrictive rod and driving coil. The result of experiment shows that the pump flow resolution records 1 ml/min~400ml/min and the maximum output pressure 0.6 MPa, which means the performance of this kind of pump is superior to ordinary diaphragm pumps.
